LP8501 Overview
The LP8501 is an LED driver with 9 outputs, designed to produce versatile lighting effects for mobile devices. The device is equipped with an internal program memory, which allows operation without processor control. Internal program memory is used by three independent program execution engines to produce user-defined lighting effects for the outputs.
